TYPE-WRITIING MACHINE.

Improvements in TypeWriters; and I do hereby declare the following tobe, a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to type-writing machines ;'and the'object of theinvention is to pe-writin machines in a number of particul ars, as wilhereinafter appear.

To. these ends my invention consists in the novel arrangement andcombinations of parts hereinafterdescribed, and particularly pointed outin the claims. I

In the drawings, A denotes the main frame, which has a top plate A, onwhich is mounted the carria e. B and: other mechanism, which will beescribed in detail hereinafter.

' The top plate is provided with suitable posts A and A and e front guie-rail A on which the carriage ovesfrom side to side :of the ma-,

stood. that the carriage is actuated by the usual spring mechanism C ina manner that need not be particularly described.

Tihecarrrage comprises a substantially rectangular frame B, providedwitha pair of traverse rollers B to run on the back rail A? and a s nglefront roller B to run on the front'rail. The carriage is held from disglac'ement on the rails by apair of brackets,

extending under the rear guide-rail, while at thefront the's'ame objectis secured'by 'a" small lug B", that extends rearwardly from the frontplate B and engages in a groove A? along the front ofthe front,guide-rail, Fig. 10., Inthe side bars of the carriage-framearedepressions B (see Fig. 1) to allow'for 'the vertical movement of thesh'aft'of the platen D as the same is shifted vertically for upper'andlower case printin he shaft D of the platen is mounted in bearingsformed in a stirrup or platen-frame E, having longitudinalconnectingbars E at the rear and E at the-bottom, as shown in Figsfl and 6.

crank-arms F, that are secured to a rockshaft F whereas the upperportion of the platen-frame is pivoted at each side'to one Thisplaten-frame is pivotally connected at the lower portion thereof to endof a link F, the opposite end ofwhich is pivoted at B to the carriage,the links i i F and crank-arms F constituting, in effect,

parallel links on which the platen-frame and platen receive theirvertical movements to change the printing position. The shiftingmechanism is best shown in Figs. 4 and 8,

wherein it will be seen that bearings onthe top plate A support arock-shaft G from which project crank-arms G, that have connected at theouter ends thereoi a sup-' porting or shift rail G, which supports aroller E", mounted in the lower longitudinal bar E of the platen-frameabove mentioned. bracket E depending from the bar E 01 the platen-framehas a lug. E 'pro'ecting under the rail Gf to prevent the roller 43 frombeing raised ofi of said rail by overthrow due to vie-- lent shifting ofthe platen or in any other manner. The rock-shaft G has connecteit toone end thereof a crank-arm G which is connected by a rod G with an armG, that projects from'one end of a rock-shaft G, that is mpunted toturnin bearings G in the frame f the machine at the front thereof. ThisI 1 5 I downwardly and forwardly rock-shaft G has secured thereto at itsopposite end a hand-operated actuating-arm G provided with a shift-key Gof the machine.

at the keyboard It will be seen that by depressing the shift-ke G theplaten-frameand platen will be e evated and on the release ,of the keythe platen and platen-frame will move to the normal position by theirown weight. The weight of the platen and platenframe is counteracted bycoil-springs F which surround the shaft 2 and tend to counterbalance theweight of the platen and plateni frame. The upward movement of the railis limited by an arm G which pro'ects from one o the center crank-armsG, abutting against an adjusting-screw G, as will be seen in Fig. 8,}whereas the downward movement of the platen and its frame may be limitedby an adjustable screw E, (see Fig. 6,) carried by v the carriage and.with which the platen-frame coeperates.

By referring to Figs. 2, 4, and 9 the mechanism for securin the'platenin shifted position Wlll be clear y se'en. An upwardly-extending arm Gmay be made as a part of the actuatin -arm G and near this arm is athree-arm lever H, pivoted to a fixed portion of the machine, oneextension 'H of which is provided with a lateral lug H that constitutesa stop adapted to intercept the arm G as the said lug is moved forwardby the upward throw of the forwardly projecting hand-operated arm of thelever H, while the upwardly-disposed arm H connects by a In H with aspring H fastened at its lower en to a fixed stud H. The construction issuch, as will be seen, that one end of the spring is moved to eitherside of the pivotal center of the lever H, and the spring holds. thelever H 1 in either position to which it may be moved tion.

around its pivot. The stud H in its forward movement engages the arm G",thereby moving and holding down the shift-key G and maintaining theplaten in its elevated posi- The step-by-step movement of the carriageis controlled by an escapement which comprises feed-dogs I and I, Figs.3, 5, 6, and 8, which cooperate with a doublynotched rack I. These partsform no essential feature of this invention, and a detailed descriptionthereof maybe omitted. It may also be noted that the lever mechanismwhich actuates the escapement also cooperates with other mechanism; butas these features are not claimed herein they need not be described. Tothe shaft of the platen is attached the usual ratchet D and this isactu- "nating in a downwardly-extending piece L. (See Fig. 4.) Acoil-spring L provided with a small antifriction-roller L.

On a bracket L connected to the latenframe E, is mounted a bell-cranklever (see Figs. 1 and 4,) provided with a de ending vertical stud L toenga e the antifi'ietionroller above described. The opposite arm of thisbell cranlg has an upwardly-extending pivot post L, that .is connectedto the arm by a vertical pivot, whereas a horizontal pivot L constitutesthe connection between the pivot-post and the rear end of a horizontally-mov able dog L, which is moved rearwardlly or in the direction ofits feed by the oscillation of the fingeriece L, while the spring Lrestores it to t e normal osition. In the rearward movement of the og Lit engages the ratchet-wheel D connected to the platen, and thus rotatesit for linespacing. I

Referring to Fig. 4, it will be seen that a shoulder L and a pin L onthe carrier of the de L engage the tail of a pawl L, which isindependent of the dog and its actuating means and is pivotedto earsprojecting forwardlyfrom the platen-frame, and the engaging nose of saidpawl L engages the teeth of the ratchet-wheel D and serves to lockthespacing dog and is positively moved thereby to effect a locking ofthe platen against overthrow or a ainst rotation in either directionwhen the 0g has about spacin movement.

To t e rear of the ratchet-wheel D is an independently-actuatedhand-operatedangular lever L", (see Fig. 7,) that is ivoted to earsextending forwardly from. tlie platenframe and the upper part of whichforms a guide L for the space-dog and to the lower part of which isconnected an elastic or re silient brake-shoe L, that is preferably madeof a stri of sheet metal. In the upper part of this lever is mounted aroller or detent L, which in the normal position of the lever L isadapted to engage the ratchet and to hold it against accidentaldisplacement, but so that the laten may he turned one or more line spaceistances in either direction. This lever is under tension of a spring L,at-

tached to the platen-frame E at one end and hearing at its freeend--against the lever and exerting a pressure thereon that tends tomaintain the (latent-roller in engagement with the ratchet-wheel and tomaintain the brake-spring out of contact therewith;

' The guide L" on the lever L has a cross:

I bar or locking-abutment li Fig. 2, that is adapted to cooperate with atransverse locking-notch L in the upperv edge of the linespace dog,where it extends through the.

guide,so.that when the operator desires to write on lines or in spacesof a blank or sheet ,that cannot ordinarily be brought to theprinting-line it is merelynecessary to raise vthefree 'end of theline-spacing dog,-thereby turning it around the pivot L". The effect Ofthis movement is to. turn the lever L on I its i'vot'against the tensionof'the-spring L teeth of the line-spacing ratchet-wheel, and

until the'brake-spring is forced against the the'detent-roller L will bythe'same movement be moved out ,of contact with thefteeth of the'wheel.By this time a slight relative movement of. the line-space dogand theguide L Will-have been effected andwhich is sufficient tobring thelocking-notch in the dog into register with the cross} bar L? of the.notch and will .bear againsttheforward end,

guide, and the cross-bar will beseatedin said wall thereof, thusmaintaining the parts in with the brake-spring bearin ,teethof theline-spacing'whee and the de the positions to which theyhave beenmoved,-

tent-rollermaintained away therefrom. At

the same time the line-spacin' mechanism is loeked against movement anthe platen is free to be rotated by either finger-wheel of the platentoth'e desired extent, .and it will V be retained in the position towhich it is retated by the brake-spring L By locking pressureexerted'upon the forward or free the line-spacing mechanism out ofactuation when the brake is applied for differential spacing thehand-lever may continue to be used to, restore the carriage to the rightwithqut,however,'at this time actuatin the line erate with theratchet-wheel, and the linespacing mechanism as a whole free to beactuated. While Iprefer to employ a lockin notch in the dog to 006 eratewith thegui e in the manner specific itshould be understood that anyfsuitable means" may be employed for this purpose. 1t .will'be seenthatthe actuation of either thie-locking-levei; L or the 'detent or brak- 7ing lever L is entirely independent of the other. I Thus the movement ofthelockingthe locking-lever is insufficient to bring the nose thereofvinto engagement with the teeth of theratchet-wheel. To-the front'part ofthe lever in no way affects the detentdever, 6o

whereas when the braking-leveris moved to a position where thebrake-spring is applied any movement; that may betransmitted to againstthe lever is pivotally connected a cam L and when turnedin eitherdirection, as indicated in Fi 7, its'hi hest. surface engages an inclineshoulder on the space-dog, and this determines the relative elevation of.said

space-dog so that the same may engage ever tooth for single spacing orevery other toot for double spacing, as will be apparent from said Fig.7 "It will be seen that the throw-of the dog L is the same whether it beemployedforsingle'or double spacing and that therefore the locking-leverwill be actuated to lock the lever-at the end of the strokeirrespecti've of'the extent of line-spac ng movement transmitted to theplaten. It is to be further noted that the construction is such that thesame movement is imparted to the spacing mechanism whether the lat-en islifted for upper-case writing or is in t e lower most position forlower-casewriting, the de pending stud L being adapted to engage withthe roll L whenthe platen is in either of said positions; asinglemovement of thefinger-piece is effective to produce theline-spacing movementof .the parts and to simultaneously move thecarriage back to the right to begin a new line.

The mechanism for disengaging the es.-

It will likewisebe'noted that capement-so that the carriage may befreely moved back and forth is best illustrated in Fig. 6, wherein itwill be seen that the dog I of the escapement is provided with'a lateralstudl and adjacent to this is mounted a" rock-shaft 1 provided with alateral wing I. This'wing connects by a, link I with a lever I, (pivotedto one side of the carriageat I, an

by pushing down 'onthefinger-piece I Fig. 1, the dog I will be thrownout of engagement with the feed-rack and the carria e is free to bemoved ineither direction;

he carriage is rovided with the usual paplaten-frame, and'theplaten-frame also has connected thereto the paper-feed rollers M, whichare mounted on a shaft supported in per-guide or tabe M, connected withthe bearin s on arms M secured to arock-shaft M". eeFig. 6.) A shortcrank-arm M end of the platen, and these-arms M each engage a lever Meach of which is also pivoted to the platen-frame and terminates at theprojects from the rock-shaft M near each" opposite side of the platenwith" the flexible 1 paper guidin and retaining arm or finger M,

- which eXten s transversely of the platen and conforms to thecurvethereof. Attached to one end of the rock-shaft M?,.-to'which the arms Mare connected, is a finger-lever M 7 (see Figs. 5 and 6,) and bypressing'down on the lever it will beseen that the pa er-feeding rollersM are moved away cm the pllaten andat the same time the crank-arms f,cooperating wlth the levers M force the guiding-fingers M away "from theplaten,

thus entirely freeing the paper, so that it may be-gnoved freely ineither direction.

tancein brackets O, which: are connected, to. a curved rock-shaft Omounted in bearings.-

O on. the frame of. the machine. The rock shaft isiplrlovidedwith asuitable finger lever 0?, by w 'ch it may be tilted, the parts beingheld to normal position by a suitable coil.- sprin 0. Near one endofthis rackbar is a stud (see Fig. 8,) which extends intothe bifurcatedend of a lever-13,: attachedto-one end of arock-shaft P, mountedin'bearings 1?,

that depend from the top plate. The other end of the shaft is-providedwith ade endinglever P pivoted to a lon itudinalFy-movable bar P, theinner end 0 which is guidedin a bearin in a bracket J, that extendsrearwardly i rom the type-bar se ment J A pawl P pivoted: to this bar,is 8.5

tr moves endwise to the right to en age the tripearm of the bell-cranklever Q, t e other arm. ofwhich forms the hammer for the bell- Q, whichis attached to the bracket J-.

When the bar P moves in the opposite direction, the cam-face of thepawlP will come in.

contact With the trip+arm and will cause the engaging end of: the pawlto be moved up around the pivot of. the pawl until it has assed thetrip, thus permitting the pawl to be moved back with the bar P withoutsounding the alarm. The rock-shaft P and the partsconneeted' thereto arerestored to normal position by a spring P.

From the foregoing description it will be understood that as the bar Nmoves longitudinally from right to left it will sound the alarm, whilethe spring P restores the parts to the normal. position when thecarriage is moved to the right. On the slide-bar are mounted slides Neach provided. with a pivoted stop N adapted to engage a projection. orstop B (see Fig. 10) of a plate B attached. to the front part of thecarriage-frame. Each.

stop N is controlled by a spring N, and theconstruction is such thatwhen the carriage moves in one direction a cooperating stop ispositively engaged; but when moved in the opposite direction the stopyields and the carriage passes over it for urposes which will presentlyappear. The s ide of each stop N is adjusted to any desired position bya dog N which engages the cooperating teeth on the rack-bar N. Theright-hand stop N constitutes a margin-stop to limit the movement of thecarriage toward the right, whereas theleft-hand stop constitutes aline-stop or a stop which limits the movement of the apted as theagainstthe tensioniof the spring P, when; the:

bell will be sounded, and. after aslight; furthen movement thecarriagewillbe arrested The operator is thus apprised of theapproaeltItothe end of the line by the'sounding of the alarm just before the endof: the. lineis reached whether the left-hand. stop. be set for a. longor short line.

It is to be noted. further that in case theline may terminate with. along monosyllable word on in any case in whioln the word mayfiverrun thelimits of the line,
